Version control of database using DVC (Data Version Control)

Data Version Control (DVC) is a data management tool that is meant to be run alongside Git. In this project, DVC is used to link changes in the code to specific versions of a sample database containing example project files. DVC can be used when this project is installed in Dev mode. You can read more about DVC and how to use it here. Note: Remote access to the sample database stored on google drive is currently restricted. Access requires a gdrive_client_secret for user access authentication to be shared by developers.

DVC usage

To download the sample database:

git pull
dvc remote modify --local shared_gdrive gdrive_client_secret <client_secret_here> # Contact developers for grive_client_secret
dvc pull # Requires access to remote storage

This will download a directory ‘db_dvc’ in the repo directory that contains the corresponding version of example database files.

To commit updates to the sample database:

dvc add db_dvc
git commit -m "Describe updates to database"
git push
dvc push #Requires access to remote storage
